STEAM JOINT.

Application led May 24, 1924. Serial No. 715,696.

To all 1li/10m. it may concern: i I, CHARLES H. ltlAnRn'r, a citizen ofthe United States, and a resident of the countypose of the condensationthereby permitting the run of the dryer to its maximum capacity.

With these and other objects in view, my invention consists in thecombination of parts shown in the accompanying drawing `fold at thefiange the plate 14 is locked into..

-'to move longitudinally and sideways. It is and described in thespecification and more particularly pointed out in the claims.

In the appended drawing,

Figure 1 is a longitudinal section through the steam joint, one line1-1, Figure 2,l

Figure 2 is an end elevation,

Figure 3 is a section on line 3--3, Figure 1, and

Figure 4 is a section on line 44, Figure 1. Y

Referring to the drawin 10 is a manifold used with rotary dryers o thetype referred to, which has a plurality of radiating steam passages 11and condensation passa es 12. (These passages are indicated in fu inFigure l and in dot and dash lines in Figure 4.) The steam passages 11 fthe manifold radiate from a central chamber 13 which is open on theouter face of the manifold. The manifold is recessed at the chamber toreceive a plate 14 of the steam 'oint. The plate 14 also fits a recessat the dange '16 of the housing 15 of the, steam joint. When the housing15 is secured to the manithe recess before referred to.

Thehousing 15 has a steam chamber 17 and a condensation chamber 18.Through thesaid chamber 18 passes a tube 19 which is screwed with oneend into ,the wall 20 of the housing 15; the other end 'of the tubepasses through the plate 14 and enters the chamber 13 of the manifold.The wall 20 carry off the condensation that is delivered lines intowhich the tube 19 is screwed separates the steam chamber 17 from thecondensation chamber 18, which chambers, as will be noted, are aligning.

Preferably. an additional bearing surface is provided for the end of thetube 19 at the plate 14, by forming ribs 18 in the enlarged portion ofthe condensation chamber 18 which enlargement is at the ange 16 of thehousing; the number of ribs 'being preferably the same as there arecondensation passages 12. Therefore, the enlarged portion of thecondensation chamber 18 is divided by the ribs into as many sections asthere are radiating condensation passages 12 and each of them isconnected to a respective section formed by the ribs 18', by a nipple21. (See Figures 1 and 4.)

The housing 15 bears snugly in a stationary sleeve 22 and through whichthe said housing 15 projects. The sleeve 22 has an annular chamber 23which leads to a threaded opening 24 adapted to receive the steam pipethrough which steam is admitted to said annular chamber 23. The housing15 hasa series of openings 24 which establish communication between thesteam chamber 17 and the annular chamber 23. Through the said openings,therefore, steam is supplied from the annular chamber to the steam S5chamber 17 of the housing.

The sleeve 22 has another annular cham, ber 25 which leads into athreaded opening 26 to which a pipe may be connected to to saidannularchamber 25 through a series of openings 27 provided in the housing 15.These openings 27 establish communication between thev condensationchamber 18 and the said annular chamber 25.

The sleeve 22 has lugs 27 which bear in slots of a fork 28 so that thesleeve, and

therefore the housing, can move up and A down in said slots of the fork.The fork is connected by a ball and socket joint 29 to a stand 30. Theball and socket joint permits the sleeve, and therefore the housing,

and the sleeve, packing glands 31 are pro- 110 vided at each end of thesleeve 22. Studs 34 connect the y,glands to the sleeve.'` The properregister of the openings 24 and 27 with the corresponding annularchambers 23 and 25, during of the housing, preferablyy providedA near`the front end of the 'steam joint. The'collar is prevented from vturningby securing it to extensions of a pair of studs 34 at the adjacent end.These means, as will be seen, will permit the rotation of the housing`of the sleeve but prevent any relative longitudinal displacement of thesleeve and the housing.

It is apparent that the plate 14 separates the steam chamber 13 of themanifold from the condensation chamber 18 of the steam joint. Inconsequence, there is no back pressure at the point where thecondensation is delivered by the manifold to the condensation. chamberl8. Therefore, the condensation from the manifold is delivered not onlyby gravity but also by the pressure of the steam which comes from thechamber 17, passing through the manifold and dryer as it tend-s to passout into the condensation passages 12 of the manifold before it canleave. This construction increases materially the ecency of the dryer,particularly when it is run to its maximum capacity, for

the heavy condensation caused 'in such instances is not blocked in thepassages of the dryer bythe back pressure at the condensation chamber ofthe steam joint housing, but, on the contrary, is forced ahead to saidchamber 'by the tendency of the steam to flow from the inlet 24 in thesleeve 22, to the outlet 2 6 of the said sleeve.
